5.5MediumCVE-2018-1000205debian · u-boot +2 moredebian u-bootU-Boot contains a CWE-20: Improper Input Validation vulnerability in Verified boot signature validation that can result in Bypass verified boot. This attack appear to be exploitable via Specially crafted FIT image and special device memory functionality.EPSS0.72%10CriticalCVE-2018-18439debian · u-boot +2 moredebian u-bootDENX U-Boot through 2018.09-rc1 has a remotely exploitable buffer overflow via a malicious TFTP server because TFTP traffic is mishandled. Also, local exploitation can occur via a crafted kernel image.EPSS2.04%7.8HighCVE-2018-18440debian · u-boot +2 moredebian u-bootDENX U-Boot through 2018.09-rc1 has a locally exploitable buffer overflow via a crafted kernel image because filesystem loading is mishandled.EPSS0.60%8.2HighCVE-2018-3968debian · u-boot +2 moredebian u-bootAn exploitable vulnerability exists in the verified boot protection of the Das U-Boot from version 2013.07-rc1 to 2014.07-rc2. The affected versions lack proper FIT signature enforcement, which allows an attacker to bypass U-Boot's verified boot and execute an unsigned kernel, embedded in a legacy image format. To trigger this vulnerability, a local attacker needs to be able to supply the image to boot.EPSS0.28%7.8HighCVE-2021-27138Alpine Linuxalpine · u-boot +3 morealpine u-bootThe boot loader in Das U-Boot before 2021.04-rc2 mishandles use of unit addresses in a FIT.EPSS1.10%7.8HighCVE-2021-27097Alpine Linuxalpine · u-boot +3 morealpine u-bootThe boot loader in Das U-Boot before 2021.04-rc2 mishandles a modified FIT.EPSS1.07%7.6HighCVE-2025-24857debian · u-boot +2 moredebian u-bootImproper access control for volatile memory containing boot code in Universal Boot Loader (U-Boot) before 2017.11 and Qualcomm chips IPQ4019, IPQ5018, IPQ5322, IPQ6018, IPQ8064, IPQ8074, and IPQ9574 could allow an attacker to execute arbitrary code.EPSS0.27%6.5MediumCVE-2025-45512debian · u-boot +3 moredebian u-bootA lack of signature verification in the bootloader of DENX Software Engineering Das U-Boot (U-Boot) v1.1.3 allows attackers to install crafted firmware files, leading to arbitrary code execution.EPSS0.33%7.8HighCVE-2020-10648debian · u-boot +3 moredebian u-bootDas U-Boot through 2020.01 allows attackers to bypass verified boot restrictions and subsequently boot arbitrary images by providing a crafted FIT image to a system configured to boot the default configuration.EPSS1.40%10CriticalCVE-2020-8432debian · u-boot +3 moredebian u-bootIn Das U-Boot through 2020.01, a double free has been found in the cmd/gpt.c do_rename_gpt_parts() function. Double freeing may result in a write-what-where condition, allowing an attacker to execute arbitrary code. NOTE: this vulnerablity was introduced when attempting to fix a memory leak identified by static analysis.EPSS3.06%7.7HighCVE-2022-2347debian · u-boot +4 moreUnchecked Download size in UbootThere exists an unchecked length field in UBoot. The U-Boot DFU implementation does not bound the length field in USB DFU download setup packets, and it does not verify that the transfer direction corresponds to the specified command. Consequently, if a physical attacker crafts a USB DFU download setup packet with a `wLength` greater than 4096 bytes, they can write beyond the heap-allocated request buffer.EPSS0.58%9.8CriticalCVE-2022-30767debian · u-boot +3 moredebian u-bootnfs_lookup_reply in net/nfs.c in Das U-Boot through 2022.04 (and through 2022.07-rc2) has an unbounded memcpy with a failed length check, leading to a buffer overflow. NOTE: this issue exists because of an incorrect fix for CVE-2019-14196.EPSS2.73%7.8HighCVE-2022-30790debian · u-boot +3 moredebian u-bootDas U-Boot 2022.01 has a Buffer Overflow, a different issue than CVE-2022-30552.EPSS0.56%5.5MediumCVE-2022-30552debian · u-boot +3 moredebian u-bootDas U-Boot 2022.01 has a Buffer Overflow.EPSS0.44%9.8CriticalCVE-2022-34835debian · u-boot +33 moredebian u-bootIn Das U-Boot through 2022.07-rc5, an integer signedness error and resultant stack-based buffer overflow in the "i2c md" command enables the corruption of the return address pointer of the do_i2c_md function.EPSS2.30%7.8HighCVE-2022-33103debian · u-boot +89 moredebian u-bootDas U-Boot from v2020.10 to v2022.07-rc3 was discovered to contain an out-of-bounds write via the function sqfs_readdir().EPSS0.46%7.8HighCVE-2022-33967debian · u-boot +3 moredebian u-bootsquashfs filesystem implementation of U-Boot versions from v2020.10-rc2 to v2022.07-rc5 contains a heap-based buffer overflow vulnerability due to a defect in the metadata reading process. Loading a specially crafted squashfs image may lead to a denial-of-service (DoS) condition or arbitrary code execution.EPSS0.56%6.4MediumCVE-2017-3226das · u-boot +3 moreDas U-Boot's AES-CBC encryption feature improperly handles an error condition and may allow attacks against the underlying cryptographic implementation and allow an attacker to decrypt the dataDas U-Boot is a device bootloader that can read its configuration from an AES encrypted file. Devices that make use of Das U-Boot's AES-CBC encryption feature using environment encryption (i.e., setting the configuration parameter CONFIG_ENV_AES=y) read environment variables from disk as the encrypted disk image is processed. An attacker with physical access to the device can manipulate the encrypted environment data to include a crafted two-byte sequence which triggers an error in environment variable parsing. This error condition is improperly handled by Das U-Boot, resulting in an immediate process termination with a debugging message.EPSS0.27%4.6MediumCVE-2017-3225das · u-boot +2 moreDas U-Boot's AES-CBC encryption feature uses a zero (0) initialization vector that may allow attacks against the underlying cryptographic implementation and allow an attacker to decrypt the dataDas U-Boot is a device bootloader that can read its configuration from an AES encrypted file. For devices utilizing this environment encryption mode, U-Boot's use of a zero initialization vector may allow attacks against the underlying cryptographic implementation and allow an attacker to decrypt the data. Das U-Boot's AES-CBC encryption feature uses a zero (0) initialization vector. This allows an attacker to perform dictionary attacks on encrypted data produced by Das U-Boot to learn information about the encrypted data.EPSS0.31%8.1HighCVE-2024-42040debian · u-boot +3 moredebian u-bootBuffer Overflow vulnerability in the net/bootp.c in DENEX U-Boot from its initial commit in 2002 (3861aa5) up to today on any platform allows an attacker on the local network to leak memory from four up to 32 bytes of memory stored behind the packet to the network depending on the later use of DHCP-provided parameters via crafted DHCP responses.EPSS0.60%
